Mueller to Reveal New Details in Manafort and Cohen Inquiries

WASHINGTON — The special counsel’s office is expected to reveal more details on Friday about separate investigations that have ensnared President Trump’s personal lawyer and his former campaign chairman.

Federal prosecutors working for the special counsel, Robert S. Mueller III, will submit a sentencing memorandum in Manhattan federal court outlining how much time Mr. Trump’s former lawyer Michael D. Cohen should spend in prison for admitting he lied to Congress. Mr. Cohen is scheduled to be sentenced next week and has agreed to cooperate with Mr. Mueller’s team as well as prosecutors in Manhattan investigating the president’s inner circle.

In the case of Paul Manafort, the former Trump campaign chairman who was convicted of financial fraud and who agreed to cooperate with the special counsel rather than face a second trial, Mr. Mueller’s team has accused him of repeatedly lying to investigators. Prosecutors pulled out of their plea deal with him because, they said, he was repeatedly untruthful. They were expected to disclose details about his falsehoods on Friday.

Mr. Mueller’s team has left open the possibility that it could file new charges for lying against Mr. Manafort. Mr. Manafort’s lawyers say he has been honest with prosecutors.

Also on Friday, George Papadopoulos, a former Trump campaign foreign policy adviser, is scheduled to be released from federal prison in Wisconsin. Mr. Papadopoulos was sentenced to 14 days after he pleaded guilty to lying to federal investigators about his contacts with Russian intermediaries during the 2016 presidential race. He was the first Trump adviser to be sentenced in the special counsel investigation.

Mr. Trump has attacked the special counsel’s investigation into whether any Trump associates conspired with Russia in the 2016 presidential election. He has repeatedly called it a witch hunt and a hoax, including on Friday, in an apparent effort to undermine public perception and trust in the inquiry.

On Friday, the president unleashed his frustration in a series of tweets, attacking Mr. Mueller and another key prosecutor on the team, Andrew Weissmann.

James B. Comey, the former F.B.I. director whom Mr. Trump fired in May 2017, was scheduled to testify privately before Congress after being subpoenaed by Republican lawmakers from the House Judiciary and the Oversight and Government Reform committees. Lawmakers are investigating possible F.B.I. wrongdoing.

Mr. Comey had initially rebuffed attempts to force him to appear behind closed doors but ultimately reached a deal with lawmakers, who agreed to make a transcript of his testimony public.

The developments cap a busy week for Mr. Mueller’s team. On Tuesday, his prosecutors disclosed that Michael T. Flynn, the president’s former national security adviser, had provided substantial assistance with several investigations. Mr. Flynn was convicted of lying to the F.B.I. about his conversations during the presidential transition with the Russian ambassador to the United States at the time.

Unlike for Mr. Papadopoulos, prosecutors have asked for little to no prison time for Mr. Flynn, the former general who served more than 33 years in the military, citing his cooperation with the special counsel.
